I tried Owncloud 5 RC3 today and setup a new server with Windows Server 2012, OC5, MySQL, IIS 8.Everything worked fine, all necessary rights were given.

If I login as admin on the local machine, I can change to the administration tab without errors.If I try to enter these tab outside of the local machine, the load time is like 1 minute and I'm getting some errors:

Because OC is written in PHP and using PHP for uploading files it needs access to the upload tmp dir of PHP (ini setting upload_tmp_dir in your php.ini) which is probably set to C:\Windows\tmp in your php.ini.

So i verified that my webserver can resolve my VirtualHosts DNS correctly. If you are behind a NAT and have some problems to connect to the external IP, you could just make a entry in /etc/hosts.... for windows i really don't know.

Setup WarningYour web server is not yet properly setup to allow files synchronization because the WebDAV interface seems to be broken. Please double check the installation guides.Module 'fileinfo' missingThe PHP module 'fileinfo' is missing. We strongly recommend to enable this module to get best results with mime-type detection.

What I've tried: - At my request, my hosting company migrated my domain to a server with PHP5.3.18 to satisfy the OC 5 dependencies. - I do not believe that the libcurl3 and libcurl3-dev libraries are installed - will check with hoster. - I've asked hoster to verify if WebDAV is allowed/configured on their end. They provide the WebDisk app through cPanel, which is a WebDAV client, so I imagine the hosting environment is fine - I've tried the php.ini fix mentioned early in this post, but that php library is already comment out in a linux (debian) config, so that didn't have an effect

I have just a couple of questions:

1 - Has anyone seen this in an OC5/linux environment, and were you able to solve it?2 - Does this problem exist in OC4.5?
